JAMES NAGLE, OF BOSTON, MASSACHUSETTS.

RAND-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 328,245, dated October 13, 1885.

Application filed February 17, 1885. Serial No. 156,142. (No model.)

To all whom it may concern Be it known that I, JAMEs NAGLE, of Boston, (Somerville,) county of Middlesex, State of Massachusetts, have invented a new and useful Improvement in Rand-Trimming Machines, of which the following is a specification, taken in connection with the drawings accompanying and forming a part hereof.

In the drawings I have shown my randtrimmer as adapted for use with a well-known form of heel-trimming machine, in which connection I prefer to employ it, in order that the work of trimming the heel and the rand may be done at the same time. It willbe obvious, however, that my device may be readily adapted to other forms of heel-trimming mechanism, or may be provided with a suitable handle and used by the operator as a hand implement.

Figure 1 of the drawings is an end view of a heel-trimmer with my rand-trimming device attached. Fig. 2 is a side view of the same. Fig. 3 is a side view of my device detached. Fig. 4 is an end view of my trimmer detached, showing its application to a shoe. Fig. 5 is a section on line as x, Fig. 4.

My invention is very simple, and will be readily understood from the following description and the accompanying drawings.

My device consists, chiefly, of two parts, a knife, (1, and a knife-holding block, b, which is fitted at one end to receive the knife, at which end it is also provided with a guard, c. This guard is so set as to project in front of the inner corner of the cutting-edge when the tool is in use, (see Figs. 1 and 2,) and protect the upper from injury by said inner edge of the knife. The block b is dovetailed at (1, Figs. 1 and 5, to receive the knife, which is provided with beveled sides throughout its length, in order that it may fit the dovetail and slide therein. The block is also split lengthwise, as shown at f, Fig. 5, and a screw, g, is set through the two parts, so that when the knife is adjusted the block may be made to clamp the knife securely in the dovetail d by tightening the screw. When the knifeedge wears down, it is only necessary to grind and reset it, and this operation may be continued until the entire blade is used. A slot, 71 in the block enables the rand-trimmer to be secured by a set screw to the heel-trimmer, and to be conveniently adjusted thereto.

It will be obvious that the rand-knife a may be of such a shape, or may be so set relatively to the block b, as to take out any desired cut from the rand. It will also be obvious that when the tool is to be used separately as a hand implement the block b will be fitted to receive a convenient handle.

What I claim is-- A rand trimming tool consisting of the clamping-block b and guard c, in combination with the adjustable knife at, having beveled sides throughout its length, whereby it may be set forward as it is ground down, for the purposes and substantially as described.

JAMES NAGLE.
